Gauze wraps - I've seen some on etsy Lilpeeperskeepers or something like that. Gypsy Mama Bali Breeze is a good gauze wrap. Both are affordable wraps.

As for smaller mamas, it's really just about getting the right size. It also depends on the types of carries you want to do. I have teeny tiny friends that use long 6's and love it! So, it really depends. I would find a wrap you love and go for it. There are materials that will feel less bulky and certain weaves that will feel less bulky. I had a Didy, but I actually found it to bee incredibly bulky, but I think it was the weave. I have a girasol and I love it. I also really like Natibaby. I think it's a great starter wrap. If you just get their stripey wrap it's very affordable and super soft right out of the package.
